Document Type and Number:
Japanese Patent JP4203697
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a radio wave propagation analysis method employing a geometrical optical analysis method, where one wireless station transmits a plurality of rays at a specific transmission angular interval and a ray arrived in a received space defined in the vicinity of other wireless station is retrieved, that relieves a calculation processing amount so as to reduce the calculation time. SOLUTION: The processing is divided into a plurality of processing sets. The analysis space is divided into a plurality of small analysis spaces in the per-processing and the middle processing (not shown in Fig.) and a storage device stores information of the ray arrived by each small analysis place. Then only the information of the specific small analysis space is retrieved in the post-processing (not shown in Fig.). Thus, number of ray retrieval processing times can be decreased, the calculation processing amount is relieved and the calculation time can be reduced.
